getLineSeparator
public String getLineSeparator()
-
setLineSeparator
public void setLineSeparator(String separator)
This will set the new-line separator. The default is
\n
. Note that if the "newlines" property is false, this value is irrelevant. To make it output the system default line ending string, callsetLineSeparator(System.getProperty("line.separator"))
- Parameters:
separator
-String
line separator to use.- See Also:
setNewlines(boolean)
-
isNewlines
public boolean isNewlines()
-
setNewlines
public void setNewlines(boolean newlines)
DOCUMENT ME!- Parameters:
newlines
-true
indicates new lines should be printed, else new lines are ignored (compacted).- See Also:
setLineSeparator(String)
-
getEncoding
public String getEncoding()
-
setEncoding
public void setEncoding(String encoding)
DOCUMENT ME!- Parameters:
encoding
- encoding format
-
isOmitEncoding
public boolean isOmitEncoding()
-
setOmitEncoding
public void setOmitEncoding(boolean omitEncoding)
This will set whether the XML declaration (
<?xml version="1.0" encoding="UTF-8"?>
) includes the encoding of the document. It is common to suppress this in protocols such as WML and SOAP.- Parameters:
omitEncoding
-boolean
indicating whether or not the XML declaration should indicate the document encoding.
-
setSuppressDeclaration
public void setSuppressDeclaration(boolean suppressDeclaration)
This will set whether the XML declaration (
<?xml version="1.0" encoding="UTF-8"?>
) is included or not. It is common to suppress this in protocols such as WML and SOAP.- Parameters:
suppressDeclaration
-boolean
indicating whether or not the XML declaration should be suppressed.
-
isSuppressDeclaration
public boolean isSuppressDeclaration()
DOCUMENT ME!- Returns:
- true if the output of the XML declaration (
<?xml version="1.0"?>
) should be suppressed else false.
-
setNewLineAfterDeclaration
public void setNewLineAfterDeclaration(boolean newLineAfterDeclaration)
This will set whether a new line is printed after the XML declaration (assuming it is not supressed.)
- Parameters:
newLineAfterDeclaration
-boolean
indicating whether or not to print new line following the XML declaration. The default is true.
-
isNewLineAfterDeclaration
public boolean isNewLineAfterDeclaration()
DOCUMENT ME!- Returns:
- true if a new line should be printed following XML declaration
-
isExpandEmptyElements
public boolean isExpandEmptyElements()
-
setExpandEmptyElements
public void setExpandEmptyElements(boolean expandEmptyElements)
This will set whether empty elements are expanded from
<tagName>
to<tagName></tagName>
.- Parameters:
expandEmptyElements
-boolean
indicating whether or not empty elements should be expanded.
-
isTrimText
public boolean isTrimText()
-
setTrimText
public void setTrimText(boolean trimText)
This will set whether the text is output verbatim (false) or with whitespace stripped as per
. Default: falseElement.getTextTrim()
- Parameters:
trimText
-boolean
true → trim the whitespace, false → use text verbatim
-
isPadText
public boolean isPadText()
-
setPadText
public void setPadText(boolean padText)
Ensure that text immediately preceded by or followed by an element will be "padded" with a single space. This is used to allow make browser-friendly HTML, avoiding trimText's transformation of, e.g.,The quick <b>brown</b> fox
intoThe quick<b>brown</b>fox
(the latter will run the three separate words together into a single word). This setting is not too useful if you haven't also calledsetTrimText(boolean)
. The padding string will only be added if the text itself starts or ends with some whitespace characters. Default: false- Parameters:
padText
-boolean
if true, pad string-element boundaries
-
getIndent
public String getIndent()
-
setIndent
public void setIndent(String indent)
This will set the indentString
to use; this is usually aString
of empty spaces. If you pass null, or the empty string (""), then no indentation will happen. Default: none (null)- Parameters:
indent
-String
to use for indentation.
-
setIndent
public void setIndent(boolean doIndent)
Set the indent on or off. If setting on, will use the value of STANDARD_INDENT, which is usually two spaces.- Parameters:
doIndent
- if true, set indenting on; if false, set indenting off
-
setIndentSize
public void setIndentSize(int indentSize)
This will set the indentString
's size; an indentSize of 4 would result in the indention being equivalent to theString
" " (four space characters).- Parameters:
indentSize
-int
number of spaces in indentation.
-
isXHTML
public boolean isXHTML()
Whether or not to use the XHTML standard: like HTML but passes an XML parser with real, closed tags. Also, XHTML CDATA sections will be output with the CDATA delimiters: ( " <![CDATA[ " and " ]]> " ) otherwise, the class HTMLWriter will output the CDATA text, but not the delimiters. Default isfalse
- Returns:
- DOCUMENT ME!
-
setXHTML
public void setXHTML(boolean xhtml)
This will set whether or not to use the XHTML standard: like HTML but passes an XML parser with real, closed tags. Also, XHTML CDATA sections will be output with the CDATA delimiters: ( " <[CDATA[ " and " ]]< ) otherwise, the class HTMLWriter will output the CDATA text, but not the delimiters. Default: false- Parameters:
xhtml
-boolean
true → conform to XHTML, false → conform to HTML, can have unclosed tags, etc.
-
getNewLineAfterNTags
public int getNewLineAfterNTags()
-
setNewLineAfterNTags
public void setNewLineAfterNTags(int tagCount)
Controls output of a line.separator every tagCount tags when isNewlines is false. If tagCount equals zero, it means don't do anything special. If greater than zero, then a line.separator will be output after tagCount tags have been output. Used when you would like to squeeze the html as much as possible, but some browsers don't like really long lines. A tag count of 10 would produce a line.separator in the output after 10 close tags (including single tags).- Parameters:
tagCount

getAttributeQuoteCharacter
public char getAttributeQuoteCharacter()
-
setAttributeQuoteCharacter
public void setAttributeQuoteCharacter(char quoteChar)

- Parameters:
args

- is the index in args to start parsing options- Returns:
- the index of first parameter that we didn't understand
-
createPrettyPrint
public static OutputFormat createPrettyPrint()
A static helper method to create the default pretty printing format. This format consists of an indent of 2 spaces, newlines after each element and all other whitespace trimmed, and XMTML is false.- Returns:
